28 year old female here. Within the past few months I have noticed that about 90 percent of the time, it feels like my heart is racing. Even when I’m resting. A couple of months ago I felt my heart racing in my chest. I had been resting for about 2 hours. I checked my pulse, and it was 92 bpm....Which I know is still in the normal range but kind of on the higher side. Since then, I always check my pulse when I feel like this. Just precautionary I guess. Well.. Yesterday.. after an hour and a half of lounging and feeling like my heart was racing.. I checked and it was at 96 bpm. But 10 minutes later..I still hadn’t moved.. and it was back down to 80 bpm.

A couple of years ago I DID have an EKG and they saw inverted T waves. Which, if I can recall, could have meant I wasn’t getting enough oxygen to the heart? Or something? But after multiple tests, my doctor said it was probably because of my “large breasts”.
